Zusammenfassung:	PURPOSE:To form a skeleton constituted of a hard and high strength material having high melting point in a Cu base by mixing specific borides and one or more kinds among Ti, Zr, their hydrides or alloys with Cu to copper powder, subjecting said mixture to green compacting and reaction sintering at the temp. or above of the melting point in copper. CONSTITUTION:One or more kinds of borides among Cr, Mo, W, V, Nb and Ta and one or more kinds among Ti powder, Ti hydride powder, Cu-Ti powder, Zr powder, Zr hydride powder, Cu-Zr powder and Cu-Zr-Ti powder are mixed to copper powder; and the mixture is subjected to green compacting. Said green compact is heated to the temp. or above of the melting point in copper and to about
